Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

One of the controversial philosophical issues of recent years has been the question of the nature of logical and mathematical entities. Platonist or linguistic modes of explanation have become fashionable, whilst abstrac tionist and constructionist theories have ceased to be so. Beth and Piaget approach this problem in their book from two somewhat different points of view. Beth's approach is largely historico-critical, although he discusses the nature of heuristic thinking in mathematics, whilst that of Piaget is psycho-genetic. The major purpose of this introduction is to summarise some of the main points of their respective arguments. In the first part of this book Beth makes a detailed study of the history of philosophical thinking about mathematics, and draws our attention to the important role played by the Aristotelian methodology of the demon strative sciences. This, he tells us, is characterised by three postulates: (a) deductivity, (b) self-evidence, and (c) reality. The last postulate asserts that the primitive notions of a demonstrative science must have reference to a domain of real entities in order to have significance. On the Aristote lian view discursive reasoning plays a major role in mathematics, whilst pure intuition plays a somewhat subordinate one."

English Renaissance Manuscript Culture: The Paper Revolution traces the development of a new type of scribal culture in England that emerged early in the fourteenth century. The main medieval writing surfaces of parchment and wax tablets were augmented by a writing medium that was both lasting and cheap enough to be expendable. Writing was transformed from a near monopoly of professional scribes employed by the upper class to a practice ordinary citizens could afford. Personal correspondence, business records, notebooks on all sorts of subjects, creative writing, and much more flourished at social levels where they had previously been excluded by the high cost of parchment. Steven W. May places literary manuscripts and in particular poetic anthologies in this larger scribal context, showing how its innovative features affected both authorship and readership. As this amateur scribal culture developed, the medieval professional culture expanded as well. Classes of documents formerly restricted to parchment often shifted over to paper, while entirely new classes of documents were added to the records of church and state as these institutions took advantage of relatively inexpensive paper. Paper stimulated original composition by making it possible to draft, revise, and rewrite works in this new, affordable medium. Amateur scribes were soon producing an enormous volume of manuscript works of all kinds—works they could afford to circulate in multiple copies. England's ever-increasing literate population developed an informal network that transmitted all kinds of texts from single sheets to book-length documents efficiently throughout the kingdom. The operation of restrictive coteries had little if any role in the mass circulation of manuscripts through this network. However, paper was cheap enough that manuscripts could also be readily disposed of (unlike expensive parchment). More than 90% of the output from this scribal tradition has been lost, a fact that tends to distort our understanding and interpretation of what has survived. May illustrates these conclusions with close analysis of representative manuscripts.

In Renaissance England and Scotland, verse libel was no mere sub-division of verse satire but a fully-developed, widely-read poetic genre in its own right. This fact has been hidden from literary historians by the nature of the genre itself: defamation was rigorously prosecuted by state and local authorities throughout the period. Thus most (but not all) libelling, in verse or prose, was confined to manuscript circulation. This comprehensive survey of the genre identifies all sixteenth-century verse libel texts, printed and transcribed. It makes fifty-two of the least familiar of these poems accessible for further study by providing critical texts with glosses and explanatory notes. In reconstructing the contexts of these poems, we identify a number of the libellers, their targets, the circumstances of attack, and the workings of the scribal networks that disseminated many of them over wide areas, often for decades. The book's concentration on poems restricted to manuscript circulation throws substantial new light on the nature of Renaissance scribal culture. As poetic technicians, its practitioners were among the age's most experimental and creative. They produced some of the most popular, widely read works of their age and beyond, while their output established the foundation upon which the seventeenth-century tradition of verse libel developed organically.

In this book I have attempted to give an account of some of the most im- portant of Whitehead's philosophical writings - his writings on the philoso- phy of science as well as his metaphysics. I have tried to show that although there are novelties in Whitehead's later philosophy there are also continuities with his earlier work in the philosophy of science. For a more detailed account of Whitehead's metaphysics, I would refer the reader to my book The Philosophy of Whitehead (The Muirhead Library of Philosophy), Allen and Unwin, London 1959 (Collier Books, New York 1962). On the whole I believe my view of Whitehead in that work, at least as far as his metaphysics is concerned, is not materially different from that held in the present one, although there are some differences in emphasis and interpretation. I wish to thank the administrateur delegue of the Revue Internationale de Philosophie, Brussels; the publishers Allen and Unwin, London; and Sprin- ger-Verlag, Heidelberg, for kindly giving me permission to publish amended versions of the following papers which I originally published with them: "Whitehead and the Idea of Equivalence" Revue Internationale de Philoso- phie, No. 56-57, 1961, pp. 167-184; "The Relevance of "On Mathematical Concepts of the Material World" to Whitehead's Philosophy", in The Relevance of Whitehead.
